This is the way I have always done mine...most the time they work out great....sometimes tho, I may pull it a little tight at the corners and it becomes a little "rounded" when the binding is flipped over to the back side. Be very careful not to make it too taught on the corners...it's easier to tuck a little bit extra in than it is to add to the corner to make it square once it's stitched on the front. Also an FYI...if you are entering into a quilt show...they want really squared corners and they also want the miters stitched down on both side of the corners. I have also always done this, but I did notice that this was on the "critique" list from the judge...who knew!
